and uncover how impact, growth, and community attract and retain top technical talent.

0:27.3

Thank you. growth and community attract and retain top technical talent. The other thing that I think about when I think about open sources,

0:29.8

you've built this community of people that are always like pressure testing your

0:33.4

software. Talk to me about security. Talk to me about why open search. I've watched a couple

0:38.3

other interviews you're in and just the security point, I think is important, more important

0:41.9

than ever before with the amount of people that do get compromised. So when you roll this out

0:48.3

and when you build an open source project, is it more secure than a closed source? Yeah, that's a great question. I think, I think, you know, it's not, it's many things. It's not just the open or closed model, right? It's the investment on security. It's, you know, your internal process. Security doesn't come down to, you know, one or two things. The way that, you know, you think about, there's sort of three principles to think about in security. One is nothing is secure. There's always going to be vulnerabilities. All you can do is kind of move those around. So that's, that's one. And when you're open source software, you have a lot of visibility and your customers are very motivated to work with you on security. Everyone runs us, you know, the secure customers. We're in public sector.

1:28.3

We're in like U.S. Air Force, right? There's like 20,000 U.S. air crews that rely on Mattermost

1:33.3

in order to fly planes. And the security and the rigor that we go through is, you know, at that level.

1:40.4

And then you'll find us in many communities that are very, very high security standard.

1:45.6

So I think that community and that understanding that, yeah, all software is vulnerable.

1:49.9

We've got transparency and people can report to us and we have a system to address that.

1:54.4

That's all super important.

1:55.5

So I think that's one on security that is for the open source model.

1:59.0

I think the second is really about the second principle, which is the effort that goes behind a breach, right, that goes behind an attack, is proportional to the value of that breach. So what that means is, you know, if you can think of like, hey, I've got everything in this giant cloud system. Like everyone in the world uses this cloud.

2:18.0

Great.

2:18.5

Guess what?

2:18.9

There's going to be like an infinite amount of like resources that will be dedicated to breaching that like mega fortress.

2:27.4

Right.
